PERFORM MANUAL SHIFTING TEST
Using this test, it can be determined whether a problem is in an electrical circuit or if it is a mechanical problem in the transmission.
If any abnormalities are found in the following test, the problem is in the transmission itself.

It is possible to deactivate the electrical shift control by disconnecting the transmission wire. The gears can then be changed mechanically with the shift lever.
